As illustrated in the following diagram, this encryption feature only applies to the link between the Oracle Tuxedo Mainframe Adapter for SNA Gateway and the CRM.

Figure 5-4 Encrypted Links

The encryptions process occurs in the following way:

1. When the Gateway establishes a connection to the CRM, the entities exchange messages to determine if encryption is enabled.
2. If both entities have encryption capability, a negotiation is performed to determine the level of encryption established.

   Each process has a range of acceptable encryption levels, as specified on the process start-up command line. The lowest common level of encryption is used.

   Note:

   When encryption is established for communications between the CRM and the Gateway, system performance may deteriorate. The higher the encryption level, the more likely deterioration may occur.
